cobverting .cpm files from 3DS?

Hi, so im super new into ripping stuff and i'm not even sure if this leads to somewhere but I still want to try it out

I just exported a lot of files through "HackingToolkit9DS", however, most of these are .cpm files. I figured out that Ohana3DS can open some of them (mostly just models) but not sprites. So is there a program that can extract/convert the sprites from a .cpm file?
Google didn't help at all, reaConverter and XnConvert couldn't convert them either.
